AI Technical Summary

Technical Problem

The prior art is difficult to effectively capture, represent and use information inside a building, including displaying visual information captured inside a building to remote users, and building plan is difficult to construct and maintain, and it is difficult to accurately scale and fill information inside a room.

Method used

By performing automatic operations using computing devices, the visual data of the images within the building is analyzed automatically generates a building plan, determines the associated location of the plan based on the image map to absolute location data, and extends the absolute location data to the surrounding building plan structural elements visible in the image.

Benefits of technology

Automatically generate and present building plan with associated absolute positions is achieved, improving building navigation and achieving high accuracy without using depth sensors.

Abstract

Techniques are described for using a data capture device at a building to automatically generate a building plan view and determine associated absolute location data for the generated plan view, such as by associating individually captured GPS data or other absolute location data with the plan view. In some cases, a building plan is automatically generated by analyzing visual data of images captured by a camera device at a plurality of image acquisition sites to determine room shapes of surrounding rooms, and associating the GPS absolute location data with the generated plan graph using additional data captured at other data capture locations of the building by a separate mobile device moving independently of the camera device, an image acquisition location and its surrounding room shape, such as by extending absolute location data from a mobile device to a camera device.
